This week at my school as a middle school "spirit" activity we're doing spirit week. Basically everyday you get to dress up a certain way to show your "spirit." lol. So basically its like this:
Monday: Celebrity Day- Dress up like a famous celebrity.
Tuesday: Twin Day- Find a buddy or two to be "twins" with.
Wednesday: Wacky Day- Dye your hair/dress up all crazily/mismatched clothes etc.
Thursday: Zodiac Day- Dress up like your Zodiac.
Friday: Stereotype Day- Dress up like a stereotype like preppy/jock/nerd/girly girl/skater/goth etc.
